Abstract
Provided are a photocuring-type three-dimensional printing device capable of automatic continuous printing, and a system. A three-dimensional model is automatically composed, the composed three-dimensional model is automatically printed and pick-up collected, and a material tank can also be automatically replenished when replenishment is needed, thereby implementing automatic continuous printing without manual intervention.
Claims20
A photocuring-type three-dimensional printing device capable of automatic continuous printing, comprising:
- an automatic printing and pick-up collecting apparatus comprising a material tank, a lifting platform, a jacking apparatus disposed in the material tank below the lifting platform, a collecting blade provided above the lifting platform, and a controller;
- wherein the material tank is configured to accommodate a photosensitive resin, wherein the lifting platform comprises distributed through holes and is configured to be connected to a molded workpiece, wherein the jacking apparatus comprises distributed ejector rods, wherein each of the distributed ejector rods is configured to pass through a respective one of the distributed through holes, wherein the controller is configured to:
- receive composed three-dimensional models,
- cause the automatic printing and pick-up collecting apparatus to print the composed three dimensional models to form the molded workpiece,
- cause at least one of the lifting platform and the jacking apparatus to move toward the other so that the distributed ejector rods protrude through the distributed through holes to separate the molded workpiece from the lifting platform and so that the lifting platform is at a position where the collecting blade can scrape the workpiece, and
- after the workpiece is separated from the lifting platform, cause the collecting blade to scrape the workpiece away from the lifting platform;
- and
- an automatic liquid replenishment apparatus configured to determine whether liquid replenishment is required, and if so, replenish the material tank with the photosensitive resin.
